Questions people ask about sales tax
- What is the sales tax rate in New Brunswick?
- New Brunswick charges 15% HST, with no separate provincial sales tax. It is collected and filed with CRA, and comes back as an input tax credit on business purchases.
- How do I work out how much tax was in a total?
- Divide the total by one plus the tax rate, which gives the amount before tax; the difference is the tax. At 13% HST, $113.00 is $100.00 plus $13.00. Do not take 13% of the total — that gives $14.69, which is wrong, and it is the single most common mistake with tax-included amounts. Switch this calculator to "find the tax inside a total" and it does it for you.
- What is the difference between GST, HST, PST, QST and RST?
- GST is the 5% federal tax. HST is the federal and provincial tax combined into one rate, charged in Ontario, New Brunswick, Newfoundland and Labrador, Prince Edward Island and Nova Scotia. PST, RST and QST are separate provincial taxes charged alongside GST in British Columbia, Saskatchewan, Manitoba and Quebec. They are administered by different governments and filed on different returns.
- Can I claim the tax I paid back?
- If you are registered, you claim GST, HST and QST paid on business purchases back as input tax credits on your return. British Columbia, Saskatchewan and Manitoba provincial sales tax is not recoverable — it is a cost of the purchase. Claiming it is a common error, and it is the reason this calculator shows the two parts separately rather than one combined figure.
- Do I have to register for GST/HST?
- You must register once your worldwide taxable revenue passes $30,000 in a single calendar quarter or over four consecutive quarters. Below that you are a small supplier and registration is optional — though registering lets you claim input tax credits on what you buy, which is often worth it if you have real expenses.
- Is QST charged on top of GST?
- No, not since 2013. Both are charged on the price before tax, so a $100 sale in Quebec carries $5.00 GST and $9.98 QST for a total of $114.98. Compounding them — charging QST on the GST-included amount — overstates the tax, and some older calculators still do it.
